Configuring the Cisco IPSec VPN Server
Cisco ISA500 Series Integrated Security Appliance Administrator Guide 233
8
• Cisco IPSec VPN Client: The Cisco IPSec VPN Client feature minimizes the
configuration requirements at remote locations by allowing the security
appliance to work as a Cisco VPN hardware client to receive the security
policies upon the VPN tunnel from a remote Cisco IPSec VPN Server. See
Configuring the Cisco IPSec VPN Client, page 238.
• Site-to-Site VPN: The Site-to-Site VPN tunnel connects two routers to
secure traffic between two sites that are physically separated. See
Configuring the Site-to-Site VPN, page 246.
• SSL VPN: The SSL VPN feature allows remote users to access the
corporate network by using the Cisco AnyConnect VPN Client. Remote
access is provided through a SSL VPN gateway. See Configuring the SSL
VPN, page 257.
• L2TP: L2TP allows remote clients to use a public IP network to secure
communicate with private corporate network servers. This protocol is
based on the client and server model. See Configuring the L2TP Server,
page 266.
NOTE The security appliance can function as a Cisco IPSec VPN server or as a Cisco
IPSec VPN client, but not both simutaneously. It does not have a default role.
Configuring the Cisco IPSec VPN Server
The Cisco IPSec VPN Server feature allows remote users to establish the IPSec
VPN tunnels to securely access the corporate network resources. It includes the
following sections:
• Cisco VPN Client Compatibility, page 234
• Configuring the Group Policies for Cisco IPSec VPN Server, page 235
